where is the xylem on a vascular bundle?
facing inward cell
where is the phloem on a vascular bundle?
in the middle of the cell
where is the sclerenchyma on a vascular bundle?
furthest part away from cell
xylem?
have cellulose in walls to allow flexibility for growth
lignin impregnates cell wall of vessel, tonoplast of vessel breaks down releasing enzymes that break down cell, end walls are lost so long hollow tubes presented.
pores in wall to allow water to leave vessel and move between
sclerenchyma?
long narrow cells that have cellulose walls (thickly lignified for strength/waterproofing)
dead hollow cells when mature and have pits in walls
phloem?
cells remain alive and transports organic soluted.
